   o  1xx (Informational): The request was received, continuing process

   o  2xx (Successful): The request was successfully received,
      understood, and accepted

   o  3xx (Redirection): Further action needs to be taken in order to
      complete the request

   o  4xx (Client Error): The request contains bad syntax or cannot be
      fulfilled

LSI keyword example

When you search for ‘bing’ in Google, Google will display a variety of documents which include the word ‘bing’. Yet, according to “https://lsigraph.com/“ it will also show semantically related terms such as the following:

  • view search history

Tiers 1, 2 & 3

Tiered link building in SEO refers to interlinking hierarchically, thus providing tiered link juice. Tier 1 links are your most powerful links. Tier 2 links are links built towards your tier 1 links. Usually these are lower quality links like automated web 2.0s and GSA spam. Tier 3 are usually trash links made by GSA and other similar tools that are pointing to your tier 2 links.
